[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] To achieve the above-mentioned objectives of the invention, such as Figure 1-3 As shown, this utility model provides a high and low brightness LED car taillight, including a heat dissipation aluminum part and a lamp plate. Multiple lamp plates are installed around the heat dissipation aluminum part, and a drive plate is installed and fixed inside the heat dissipation aluminum part. The tail cover is screwed onto the heat dissipation aluminum part. An adapter plate is fixedly provided at the end of the heat dissipation aluminum part away from the tail cover. A fan is fixedly provided on the outside of the adapter plate by adhesive.
[0031] In this embodiment, one end of the driver board is connected to the vehicle controller. The interface on the driver board that connects to the vehicle controller is divided into a high-brightness interface and a low-brightness interface. The other end of the driver board is connected to the adapter board, which in turn connects to the lamp board attached to the heat sink aluminum component. In this way, the controller inside the vehicle controls the switch and brightness of the lamp board through the driver board. Moreover, the driver board, adapter board, and lamp board are connected by printed circuit board pads, eliminating the need for wire connections. The structure is compact, easy to assemble and produce, and convenient to use. It can effectively reduce resource waste and lower production costs.
[0032] In this embodiment, a fan is installed inside the LED car taillight. This fan is a cooling fan. When the LED car taillight starts working, the fan blows air onto the driver board and the lamp board, which can dissipate the heat generated between them in a timely manner, thereby enabling the entire LED car taillight to work better.
[0033] Preferably, an aluminum rear cover is screwed onto the adapter plate, and the fan is located inside the aluminum rear cover. In this way, the aluminum rear cover can better protect the operation of the fan.
[0034] like Figure 3 As shown, the fan includes a housing, a motor, and fan blades. The motor is fixed inside the housing by a bracket. One end of the motor is connected to the fan blades through an output shaft. The motor drives the fan blades to rotate through the output shaft. The motor is electrically connected to an external power source through a power cable. In this way, the fan can better achieve heat dissipation inside the LED car taillight.
[0035] Preferably, the shell is a hollow cylindrical structure.
[0036] Preferably, the fan is fixed to the adapter plate by adhesive, thus achieving fan fixation.
[0037] Preferably, the lamp panel has four lamp panels, which are fixed to the heat dissipation aluminum component by welding.
[0038] Preferably, the entire frame structure of the LED automotive taillight is made of aluminum, which has better heat dissipation performance and avoids rusting.
